Yukihiro "Matz" Matsumoto f22a991065 build: pick first matching ports/<name>/ per gem ...

When `conf.ports` was given multiple names, every matching ports/
directory for each gem was compiled -- fine for single-name builds
and for gems that have at most one matching port, but a footgun
once HAL-using gems start providing multiple alternative ports
(e.g. mruby-task with both posix and an alternative runloop).

Iterate the chain and break on the first match.  Existing builds
that pass at most one name per gem keep the same behavior;
`conf.ports :rp2040, :posix` now reads as "use rp2040 if a gem has
that port, otherwise posix" rather than "compile both".
